SJRA Releases Third Part of Sedimentation Study

In late December 2023, the San Jacinto River Authority (SJRA) released the third part of its massive, years-long sedimentation study. SJRA labeled the report “Technical Memorandum 3: Annual Sediment Supply and Storage.” Only seven more steps remain in the 10-step effort. The Larger Context The ten steps include: SJRA applied for a TWDB grant to […]

Harris County Flood Control, Montgomery County, the SJRA, and Texas Water Development Board are searching for sediment solutions in the Upper San Jacinto River Basin. Their major scientific study includes all or parts of six counties: Harris, Montgomery, Waller, Grimes, Walker, San Jacinto and Liberty – all land draining into Lake Houston. The high-level goal: […]

Colony Ridge Stormwater Detention Basins, Ditches Fail to Meet Liberty County Standards

Colony Ridge, the world’s largest trailer park, fails to meet Liberty County regulations for the construction of stormwater detention basins and ditches. The development’s basins and ditches routinely lack erosion controls such as grass and backslope interceptor swales. The resulting erosion can reduce the conveyance of streams, increase flood risk and threaten property both inside […]

The Hand of Sand Miners on the San Jacinto

The hand of sand miners weighs heavily on the San Jacinto watershed. Not all miners. But many. While exploring the river basin by helicopter last week, the contrast between two scenes struck me: 1) The natural blanket of green in Lake Houston Wilderness Park. 2) Sand mines that lined the banks of the East and […]

Controversial Colony Ridge Development Doubles in Size

The Colony Ridge development in Liberty County, aka the world’s largest trailer park, has more than doubled in size in the last 3 years. Measurements in Google Earth show that Colony Ridge, which started clearing land in 2012, has expanded from approximately 8,000 acres in 2019 to almost 20,000 acres today. To put that in […]

How Soon We Forget!

How soon we forget. Hurricane Harvey was just 4.5 years ago. Since then I have documented dozens, if not hundreds of questionable practices that erode margins of flood safety. It Didn’t Have to Be That Bad Harvey was the largest rainfall event in the history of North America. However, with better regulations and construction practices, […]

San Jacinto Master Drainage Plan Uses Gage UPSTREAM from Sand Mines to Estimate West Fork Sedimentation

Appendix F of the San Jacinto River Basin Master Drainage Plan discusses the sediment contribution to Lake Houston of various tributaries. It asserts that Cypress Creek, Spring Creek, and West Fork sub-watersheds are the highest contributors of suspended sediment to Lake Houston, contributing an estimated 38.7 percent, 26.8 percent, and 13.0 percent of the total […]
